Abstract

Improvements to the retention means, particularly for ball valves, according to which a valve is constituted equipped with a bolt or guide rod guided in the corresponding sleeve of the valve body and having an intermediate collar with a flat upper and lower surface and parallel, comprising a first and a second pair of wedge-shaped cross-section annular gaskets (10-10') - (11-11'), in the first of which it is arranged between the bottom stop -8- of said sleeve -5- and the flat bottom surface of said intermediate collar of the bolt and the second between the flat top surface of said collar and the inner end of a clamping bush -9-threaded in said sleeve, housing the two annular fittings of each pair partially with each other, to be coordinated along a circumferential contact surface in an inclined plane and in such a way that the interior can It can slide on the exterior, and with respect to it, along said inclined contact surface.
